Harrelson has been vegan for nearly three decades, <a href="http://features.peta.org/sexiest-vegetarian-celebrities-2012/">according to PETA</a>. He had his "aha" moment when he was trying to make it as an actor in New York: "I was on a bus and some girl sees me blowing my nose, I had acne all over my face, which I'd had for years and years. And she's like: 'Hey, you're lactose intolerant. If you quit dairy, all these symptoms you got will be gone in three days.' I was like 24. And I was like, No way. But three days later: gone." <a href="http://features.peta.org/sexiest-vegetarian-celebrities-2012/">He was named PETA's Sexiest Vegetarian Celebrity of 2012</a> alongside Jessica Chastain.
